Answer:
<h2>81.28</h2>
Step-by-step explanation:
To solve this kind of problem, we must remember that the word "of" means multiplication in math language, and all percentages numbers can be expressed as a fraction where the denominator is 100. Applying all this, we have
Therefore, all those percentages of 8128 results in 81.28
Answer:
C(x) = 5x + 20 (for members)
C(x) = 3.5x (for non-members)
Step-by-step explanation:
Cost of membership = $20
Price of a game per month = $5
So, the linear equation to compute the total cost for a member can be computed by:
C(x) = 5x + 20
where x is the number of games per month
On the other hand, non-members can get one more game per month for $7 which means they get 2 games for $7. The price for a single game is $7/2 = $3.5 a month.
The linear equation to compute the total cost for a non-member is:
C(x) = 3.5x
where x is the number of games per month.
The following system of equations can be used to decide whether to become a member or not, by substituting the number of games in place of x and finding out the total cost.
C(x) = 5x + 20 (for members)
C(x) = 3.5x (for non-members)
Answer:
£84
Step-by-step explanation:
The given ratios are ...
A : N = 2 : 1
N : J = 3 : 1
Putting these together, we have ...
A : N : J = 6 : 3 : 1
There are a total of 6+3+1 = 10 ratio units, so each is worth £140/10 = £14.
Angad's share is 6×£14 = £84.
_____
<em>Check</em>
Nick gets £42, and June gets £14. Together, they share £84 +42 +14 = £140.
